Using STM32H735, Can I play any video clip?

TouchGFX has video clip play example for STM32H735-DK EVB.

But It is not working.

Probably not

Video comes in many formats, you'd need a suitable decoder for each format you want to use, or transcode on the PC into a supported format. Most are encumbered with IP and licensing costs, and may not be efficient without hardware assistance.

Likely only MJPEG

In case of MJPEG, Can STM32H735 play the MJPEG video clip?

Not sure, I don't see reference to the JPEG CODEC that's on other H7's including the H7B3

The MCU can't do much without appropriate software.

Thank you for answer. 🙂

Hello JKim.51,

I confirm for this board, the video decoding is not supported. Indeed, it requires JPEG codec and this board has not. We have an article talking more about video decoding, I invite you to have a look on it if you're interested.

well, you can play video, if your TFT has any controller, which is supporting video/decoding , so the cpu has not so much (or too much 🙂 ) to do;

i have here 7" TFT, 800x480 pix, with EVE controller and SPI connected to stm32H7A3 board;

read about displays with such controller, so you can play video ;

and the library i use is by Rudoph :

In it simplest form video can just be the dumping of frames into the frame buffer. The volume of data can become quite high​, and then you use compression methods as a means of balancing data volume vs processing bandwidth.
